Description:
<jats:title>Abstract</jats:title><jats:p>We describe the preparation and characterization of uniaxial magnetic gels. Fibril formation of the embedded magnetic particles generates easily detectable magnetic and optical anisotropies. A finite magnetization is frozen‐in and leads to a ferromagnetic‐like response in small homogeneous external magnetic fields. We present, for the first time, frequency dependent measurements of the shear modulus <jats:italic>G</jats:italic>′. Despite their optical and magnetic anisotropy, the gels are mechanically isotropic.</jats:p><jats:p><jats:boxed-text content-type="graphic" position="anchor"><jats:caption><jats:p>The time‐dependent <jats:italic>G</jats:italic>′ for a ferrogel in the parallel orientation in a homogeneous field of 200 mT.</jats:p></jats:caption><jats:graphic xmlns:xlink="http://www.w3.org/1999/xlink" mimetype="image/gif" position="anchor" specific-use="enlarged-web-image" xlink:href="graphic/mgra001.gif"><jats:alt-text>magnified image</jats:alt-text><jats:caption><jats:p>The time‐dependent <jats:italic>G</jats:italic>′ for a ferrogel in the parallel orientation in a homogeneous field of 200 mT.</jats:p></jats:caption></jats:graphic></jats:boxed-text>
